Yes, Twentieth Century Fox is reportedly in negotiations to develop Starlight as a feature, where Millar serves as the studio's consultant on their Marvel feature film properties the X-Men and Fantastic Four and where his Secret Service is also in development to be directed by Matthew Vaughn and to star Colin Firth.

The ever-increasingly busy Simon Kinberg will write the script and produce the adaptation, according to The Hollywood Reporter. Kinberg has or will have his hand as writer and/or producer of X-Men: First Class, next year's Days of Future Past, and 2016's X-Men: Apocalypse (as well as overseeing the expansion of Fox's X-verse) along with Fox's Fantastic Four reboot, co-writing/producing Star Wars: Episodes VIII and IX, solo writing a Star Wars spin-off solo film, and serving as one of three EPs on the animated series Star Wars: Rebels.

Kinberg is also reportedly producing an adaptation of Millar’s Kindergarten Heroes, which has Carter Blanchard attached as writer.

Millar has described Starlight “Flash Gordon-meets-The Dark Knight, centering on a space hero who saved the universe 35 years ago but came back to Earth, where no one believed his fantastic stories. He settled down, got married, had kids and got old. And then that old, sparky Buster Crabbe-era rocket-ship comes back and needs him for one last adventure. It's Buzz Lightyear meets Unforgiven.”
